Hi, I just downloaded the boost 1.58 beta. Tried to build with: ./b2 --with-filesystem --with-system --with-atomic --with-chrono --with-date_time --with-program_options --with-regex --with-test --with-thread --with-random --with-context --with-coroutine variant=release link=static runtime-link=static threading=multi toolset=gcc cxxflags=-Wno-unused-local-typedefs install Got the following error: Performing configuration checks     - 32-bit                   : no     - 64-bit                   : yes     - arm                      : no     - mips1                    : no     - power                    : no     - sparc                    : no     - x86                      : yes     - lockfree boost::atomic_flag : yes     - lockfree boost::atomic_flag : yes     - has_icu builds           : no error: Name clash for '

libboost_system.a' error: error: Tried to build the target twice, with property sets having error: these incompabile properties: error: error:     -  none error:     -  <address-model>64 <architecture>x86 error: error: Please make sure to have consistent requirements for these error: properties everywhere in your project, especially for install error: targets. Some googling reveals that people suggest adding '--without-context --without-coroutine' to work around the problem, but this is not an option for me because I use these libraries! What can I do to fix this? Thanks, Nate
